Why don't you just look at replacing the bars?
I've clicked on a bunch of handlebar web pages. If I could somehow find and
pick "the right set", that would probably do the trick. I wish there was a
"handlebar superstore" down at the corner, I'd take my bars off and go
down there and compare them until I found the right ones... is there someplace
in Atlanta where they have 100 sets of handlebars on display? I guess I
could measure the OEM bar's overall-width, center-width, pullback size and
height and just try to pick from a web page...
My extra set of OEM risers (well, the left one) came yesterday. They're each different,
with these LED-pod mounting tabs on them...

The way they plug into the rubber mounts is not something that is going to
"unscrew" from the riser itself...

There's a bunch of Harley risers that fit into similar rubber mounts, but there's
little chance that they are the same size. Plus, the mounting tabs wouldn't be there.
Someone's going to have to make special Honda Valkyrie risers, or else these
are it.
